arm64: dts: allwinner: a100: Add EMAC support

Browse Source 
The Allwinner A100/A133 Ethernet MAC (EMAC) is compatible with the A64
one and needs access to the syscon register for control of the
top-level integration of the unit.

Note that there are two such controllers on the sun50iw10 die, which are
the same unit with a different top-level syscon register offset.
